PENCIL-SHABPENER.

Specification of Letters Patent.

Patented Feb. 6, 1217.

Original application filed October 20, 1915, Serial No. 56,924. Divided and. this application filed March 31,

To all whom it may concern:

Be it known that 1, James H. Born, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful improvements in Pencil- Sharpeners, of which the following is a specification.

This invention relates to lead pencil sharpeners of the character disclosed in my application No. 56,924, filed October 20, 1915.

The primary object of the present invention is to provide an improved device for sharpening the lead of the pencil. after the wood has been pared.

The invention is illustrated in its preferred embodiment in the accompanying drawing, in which Figure 1 represents a perspective view of my improved lead-pcncil-sharpener, the view showing a pencil undergoing the woodparing operation; Fig. 2, a perspective view of the device, showing the opposite edge; Fig. 3, a perspective view of the device with the container partially open; Fig. 4-, a sectional view taken as indicated at line 4. of Fig. 3; Fig. 5, a broken sectional View of the wood-paring device, shown removed from the casing, or container-holder, and. illustrating the manner in which the wood is pared from the lead of the pencil; Fig. 6, a longitudinal vertical section taken as indicated at line 6 of Fig. 4, but showing the container-holder closed; and Fig. 7, a transverse section taken as indicated at line 7 of Fig. l.

The invention, in its preferred embodiment, comprises a container-holder A; a combination pencil-guide and wood-paring device B, located in and carried by said contamer-holder; and a lead-abrader or abrasive lead-sharpening device, C, located in and carried by said container-holder.

The container-holder A, as the name implies, is adapted to serve as a containerholder for the elements B and C, and also as a container for the wood-parings and lead removed from the pencil in the sharpening operations. No claim is made in the present application, however, to the wood-paring device.

The containenholder A preferably comprises an open top box 1, and a slightly larger box-form closure, or cover, 2, which Serial No. 87,933.

receives the b0 1 telescopically, the two members being connected near one end, by pivots 3.

The container-holder is preferably of the rectangular form shown, and may conveniently be made of a length of a couple inches, and of a width of about one inch and a quarter. The box 1 has upturned narrow flanges, the lateral flanges being provided. near the end distant from the pivots 3 with semicircular recesses l.

The cover 2 has downturiicd flanges of somewhat greater depth. The casing may be opened by pressing together the ent s of the members 1 and 2, which project back of the pivots 3, thus separating the opposite ends of said members.

The device B comprises a pencil-guide .1-. disposed between the lateral flanges of the cover 2 and equipped at its tapered portion with a sharpening blade The device B is adapted to pare the wood of the pencil 5 without cutting the lea d The lead-point ing device C, in the form illustrated, comprises a pair of file-toothed, springheld, jaws 6 and 7, which are disposed beneath or suspended from the top wall of the easingmember, or cover, 2. The file-members 6 and 7 have curved shank-portions securely fastened to the spring arms 8 of a member, or clip, 8*, which has an attaching portion 9 secured to the top wall of the casing-member 2, as by rivets 9. The spring-arms and the clip may be integrally formed; and the file-members may be secured to the springarms by having their shanks secured or c011- fined between the bodies of the spring-arms and the members 8 which are struck from the arms by incising the metal and stamping the severed portion to the form desired. The file-members 6 and 7 are made concavoconvex, with their convex portions opposed to each other and the extremities separated, to afford between them a space 10, which registers with a hollow tapering guidemember 11 carried by one of thelateral flanges of the cover 2. The corresponding flange of the box 1 is recessed, as indicated at 1*, to accommodate the guide-member 11.

After the pencil D has been inserted in the guide B, and turned therein to pare away the wood and leave the lead 5, the pencil is withdrawn from the device B, and the lead is then inserted through the guide 11, which registers with a perforation 11 in the lat eral flange of the cover 2; and the lead is pointed by a reciprocating motion thereof between the spring-held filemen1bers 6 and 7. The divergent end-portions of the filemembers are preferably smooth, and the pointing of the lead is effected between the roughened convex portions. By the use of the opposed, spring-held file-members it is possible to secure a rapid sharpening operation by a simple longitudinal reciprocation of the pencil, accompanied by occasional slight rotary oscillation.

The fine shavings, or wood-parings, are deposited in the box, and the particles of lead removed by abrasion are received in the same chamber. In practice, the lead parti cles are sifted through and mixed with the parings, and there is sullic-ient allinity be tween the wood and lead particles to prevent the lead particles from sitting out through the openings of the casing.

On oc :asion, when it may be necessary, the container may be opened by pressing together the rear ends of the box-form members comprising the casing, thus permitting the contents to be dropped into a waste basket. The device may be freely handled, and the pencil-sharpening operation may be performed Without soiling the hands.

The device described is simple, thoroughly effective, and may be cheaply manufactured.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom.

lVhat I regard as new, and d'esire to secure by Letters Patent, is-

l. A pencil sharpener comprising a container-holder having an opening in one wall and a registering guide projecting inwardly from said wall, and a pair of spring-held opposed file-members, located in said container-holder and having separated extremities disposed in alinement with said guide.

2. A pencil sharpener comprising a container-holder, a pair of sprlng-arms carried thereby, a pair of opposed file-members confined between sa d spring-arms and having oppositely turned extremities affording a.

space between them, and a taper guide-member carried by one wall of said casing, and having its inner end in alinement with the space between said file-members.

A pencil sharpener comprising a container-holder having one wall provided with a perforation and equipped with a tapering guide, a pair of opposed file-members having diverging extremities affording between them a space in alinement with said guide, a pair of spring-arms carrying said file-members, and means securing said spring-arms to a wall of said container-holder.

4. A pencil sharpener comprising a holder, a pair of opposed file-members, spring-arms between which said fileniembcrs are confined, and a tapering pencil gniderarried by said holder and disposed in alinement with the space between said file-members.

A sharpening device comprising a holder element, a pair of spring-arms car ried thereby, a pair of filen1embers having opposed concavo-convex portions and diverging extremities, said file-members carried by said spring-arms and having smooth adjacent surfaces at their extremities, and atapering pencil guide carried by said holder and disposed in alinement with the space between said file-members. V

6. A sharpening device comprising a box, a cover pivotally united thereto, a clip secured to the inner side of said cover and carrying a pair of spring' arms, and a pair of file-members carried by said spring-arms and having opposed concave-convex portions and diverging extremities, one flange of said cover having an opening in alinement with the space between said file-memhers.
